NO:

Repair the CAN bus line. Refer to GROUP 54D, Can bus

Diagnostics Table P.54D-10. Then go to Step 2.

STEP 2. Recheck for diagnostic trouble code.
Check again if the DTC is set.

(1)

Erase the DTC.

(2)

Turn the ignition switch to the "ON" position.

(3)

Check if DTC is set.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is DTC U1180 set?

CIRCUIT OPERATION

｠

Battery voltage is applied to the diagnosis
connector (terminal No. 16).

｠

The diagnosis connector (terminal No. 4 and No. 5)
is grounded to the vehicle body.

COMMENT

｠

When the communication between M.U.T.-III and
ECM is impossible, it can be suspected that the
CAN bus line, power supply circuit of the diagnosis
connector, and/or grounding circuit are defective.

｠

Communication can not be achieved either, if a
wrong vehicle type is selected on M.U.T.-III.
